Sluggish top end speed
I have a 2002 Jeep Wrangler with a 1999 in line 6 engine bet in February 8 lost a freeze plug and the engine started knocking. I had the engine rebuilt but I have no top in speed. The lower gears are peppy enough but my max speed is 65 & I have to work to get it to that speed. Highway driving is constantly downshifting and the petal to the metal.
I think it came with 15" tires & I replaced with rubicon 17" wheels & BFG mud terrain. Any suggestions why it has not pep in overdrive?
